Killzone 2 [BCES00081]

While I'm playing the US version, but it might be helpful to this version as well.
I found disabling anti-aliasing can give a huge performance boost. With anti-aliasing set to "auto", it would max out my 1080Ti and still only has 10~14fps; with it disabled, even at 4K, it only uses 40~50% GPU, and has double the fps, getting close to 30fps in smaller, less busy scenes.

It seems that I already disabled it but I don't remember what difference it made to performance - good to know that playable speeds ARE achievable if you have the specs though :-)
